Slide 2

Cpu,s

Slide 3

Cpu - function the cpu is located on the mother board and can also be called the central processing unit or the processor. In terms of computing the cpu is the single most important element in a computer. The cpu is like the brain of the computer it processes all the machines information.

Slide 4

Cpu-brands There are two main cpu companies intel and amd Amd cpu,s are cheaper but they have less power Intel costs more but your paying for more power in a cpu

Slide 5

Cpu-GHz The power for a cpu is usually measured in gigahertz most computers operate at about 4 gigahertz Some people push cpu,s to operate at more gigahertz but more on that later

Slide 6

Cpu-cores A core is like a processor inside of another processor cpu,s can have anywhere from 1 to 8 cores The more cores you have the faster your computer For example if you have a computer you will use for video editing you may want to have a 6 or 8 core processor

Slide 7

Cpu- purchasing considerations Cash memory(memory on the cpu) Compatible with mother board Clock speed Number of cores

Slide 8

Cpu-overclocking Over clocking is when you push you r cpu past its limitations This sounds great but it can be dangerous for your computer if you push it too far it could blow up Intel does offer a partial warranty but for the most part overclocking is not condoned by cpu companies

Slide 9

Cpu-Hyper threading Hyper threading is a way for the processor to bring one thing up if you have something else open This feature is not available on all processors but is a major add on of the ones that do have it This can be very helpful if used correctly because it prepares what you will need next

Slide 10

Cpu- my personal choice I would probably pick the intel i7-377OK The reason for this being that this processor has 4 cores,offers hyper threading and has good performance

Slide 11

Motherboards

Slide 12

Motherboard-function the motherboard is the central part of the computer where everything meets and is connected.

Slide 13

Motherboard-ram Ram is short for random access memory it is your computers memory. Ram is located on the motherboard and what you can do is limited to the amount of ram you have.

Slide 14

Motherboard-form factor Form factors are the 4 different motherboard sizes. ATX, BTX, micro ATX and mini itx ATX being the biggest mini itx being the smallest the BTX and the micro atx are somewhere in the middle.

Slide 15

Motherboard-socket types o The socket is the place where the cpu will go in on the motherboard. o There are many types of sockets for motherboards make sure the one you get will be compatible with the cpu you will use. o Some examples of sockets are the lga772 or the am2

Slide 16

Motherboards-drive connections There are 3 drive connections Sata, ide and raid I will talk about each here Sata- the cable used to connect hard optical and floppy drives to the motherboard Ide- used to connect drives to the motherboard before being replaced by the faster, smaller and neater Sata cables. raid- stands for redundant array of inexpensive disks and allows you to either combine smaller drives into 1 big drive or use several drives to mirror or back up data for added security.

Slide 17

Motherboards-expansion slots Expansion slots are used to outfit your computer with capabilities it might not have been designed with such as graphics or sound cards.

Slide 18

Motherboards-rear panel ports There are 5 rear panel ports the Keyboard and mouse ports, the eSATA ports, the Ethernet port, the USB/FireWire port and the Serial/parallel ports Rear panel ports are located on the back of the computer case in the rear panel

Slide 19

Motherboard-my personal choice My personal choice would be the gigabyte GA-Z68M-D2H The reason for this being that it is note very expensive but it has 4 ram slots and 32 gb,s of memory

Slide 20

Ram (random access memory)

Slide 21

Ram-function Ram is your computer's memory it could not function properly without it. How fast you can do something depends on how much ram you have.

Slide 22

Ram-purchasing considerations When buying ram you need to remember 5 things Quality- good quality ram will work in your computer for a long time Value make sure you are getting the best value for the best price Compatibility-will your ram work with your computer

Slide 23

Ram-when is additional needed If your pc is running slow or seems kind of sluggish you should probably consider getting more ram.

Slide 24

Ram-my personal preference My personal choice for random access memory would be the AD2S800B2G5-R. Because it offers plenty of memory and people who used it have said good things about it

Slide 25

Video card

Slide 26

Video card-function The video card allows you to see an image on your computer screen.

Slide 27

Video card-purchasing considerations Here are some things to keep in mind when shopping for a video card. Graphics processing unit-determines video capabilities Memory and clock speed Length of video card- some video cards take up more space

Slide 28

Video cards-my personal choice I would pick the GTX770-DC2OC-4GD5 I would pick it because people who use it have given it good ratings and it has 4 gb of storage.

Slide 29

Power supply

Slide 30

Power supply-function The power supply is the most important part of the computer with out it nothing works. The power supply plugs into the motherboard and powers the entire computer.

Slide 31

Power supply-purchasing considerations Things to look for when buying a psu Wattage Which connectors you need High efficiency rating Robustness of psu Number of rails Get a modular psu Compare the amperage of each voltage

Slide 32

Power supply-my personal choice I would pick the antec hcp-1300 platinum It has a good wattage and people who have used it gave it an excellent rating

Slide 33

storage

Slide 34

Storage-function The place where all the information for the computer is stored

Slide 35

Storage-purchasing considerations Things to consider when buying storage Reliability Performance Storage space

Slide 36

Storage-failure Hard drives can and will fail so you should always have a reliable back up system

Slide 37

Storage-my choice I would pick the Crucial MX100 256GB

Slide 38

Case

Slide 39

Case-why do we need it Cases hold the motherboard and all of the hardware needed to make your computer work.

Slide 40

Cases-purchasing considerations When buying a case for your computer there are some things you need to keep in mind. Case size-there are 3 case sizes mid tower(the most common), full tower(the biggest) and mini tower(the smallest) each fits different sized motherboards. Price range- mini towers are less expensive(25 to 80 dollars) but the more expensive full towers full towers can fit more components if need be however if you spend more money on a case it will be of better quality You also have to chose between screws and snap in component areas. Access to components fans built in etc. The last factor is what you want the case to look like.

Slide 41

Case-my personal choice I would go with the Aero cool DS-Cube Blue It is compatible with my components and has good performance.

Slide 42

Cooling devices

Slide 43

Cooling devices-types Cooling devices include: Fans- draw cool air to the case from outside the bigger the fan the quieter the machine Liquid cooling systems-draws heat to it making the computer colder Heat sink-disperses heat

Slide 44

Cooling devices-purchasing considerations Things to keep in mind when buying a cooling system: budget Space Experience Size of the fan- bigger fans make computer quieter
